A long series of evenly spaced lights (about 15+ on each side) which moved slowly.

The shape was incredibly long (30-50 ft.)with lights on each side. The lights were spaced uniformly on each side. It looked like a faint cigar shape, very long and thin. The lights were bright as a star. We were able to watch it move slowly, tilted in a vertical direction and then it disappeared as if behind something, but nothing was there. The lights were very bright, and they dimmed as it started to ascend. We both watch the sky, and we have never seen anything like this. No other aircraft was around at the time. When we first saw it was so bright, and started to move as we both looked at it, dimmed and disappeared. It lasted no more then 5 minutes.
